摘要

PROBLEM TO BE SOLVED: To obtain the subject novel compound that is a specific 2,3,6,7,10,11- hexakissilyloxytriphenylene compound and is useful as a synthetic intermediate for triphenylene derivatives as a liquid crystal material because this compound has excellent solubility and permits easy desilylation. ;SOLUTION: This compound is a novel 2,3,6,7,10,11-hexakissilyloxytriphenylene represented by formula I (R₁-R₆ are each a silyl group), shows good solubility in an organic solvent and can be readily purified by recrystallization and is useful as a starting substance for producing high-purity 2,3,6,7,10,11- hexahydroxytriphenylene that is a synthetic intermediate for triphenylene derivatives to be used as liquid crystal materials. The compound is prepared by dissolving 2,3,6,7,10,11-hexahydroxy-triphenylene in tetrahydrofuran and adding N,N-dimethyltrimethylsilylamine or the like to the solution to effect the reaction between them.;COPYRIGHT: (C)1999,JPO
